Abstract

A spring clip for a flat flexible cable includes a first beam and a second beam connected to the first beam and resiliently deflectable toward the first beam. The second beam has a first contact bend extending toward the first beam. The flat flexible cable is positioned between the first beam and the second beam and the first contact bend abuts a conductor exposed through an insulation material of the flat flexible cable to electrically connect the spring clip with the conductor.

First claim

What is claimed is:

1. A connector assembly, comprising:
a flat flexible cable having an insulation material and a conductor embedded in the insulation material, the conductor is exposed through a portion of the insulation material; and
a spring clip having a first beam and a second beam connected to the first beam and resiliently deflectable toward the first beam, the second beam has a first contact bend and a second contact bend extending toward the first beam, the second contact bend is positioned between the first contact bend and a free end of the second beam, the flat flexible cable is positioned between the first beam and the second beam and the first contact bend and the second contact bend resiliently abut the conductor to electrically connect the spring clip with the conductor.

2. The connector assembly of claim 1 , wherein the first beam and the second beam are connected at a connection section and extend away from the connection section, the first beam has a free end opposite the connection section and the free end of the second beam is opposite the connection section.

3. The connector assembly of claim 2 , wherein the first beam, the second beam, and the connection section are monolithically formed in a single piece.

4. The connector assembly of claim 2 , wherein the connection section is a curved portion about which the second beam is resiliently deflectable.

5. The connector assembly of claim 2 , wherein the connection section is a pin interface adapted to electrically connect to a contact pin.

6. The connector assembly of claim 2 , wherein the second beam has a friction lock at the free end, the friction lock including a bent portion of the second beam bent back toward the connection section and the first beam.

7. The connector assembly of claim 6 , wherein the bent portion of the friction lock ends in an edge electrically and mechanically engaging the conductor exposed through the insulation material of the flat flexible cable.

8. The connector assembly of claim 1 , wherein the first beam has a plurality of serrations on an interior surface facing the second beam, the serrations engaging the insulation material of the flat flexible cable.

9. The connector assembly of claim 1 , wherein the first beam has a piercing element extending from an interior surface toward the second beam, the piercing element extends through the insulation material and electrically and mechanically engages a side of the conductor opposite the first contact bend.

10. The connector assembly of claim 1 , wherein the first beam has a contact protrusion extending from an interior surface toward the second beam, the contact protrusion extending through a window in a portion of the insulation material and electrically contacting a side of the conductor opposite the first contact bend.

11. The connector assembly of claim 1 , wherein the first contact bend abuts a side of the conductor exposed in a stripped section of the flat flexible cable in which the insulation material is removed from a side of the flat flexible cable.

12. The connector assembly of claim 1 , wherein the first contact bend extends through a window in the insulation material exposing only a portion of the conductor to abut the conductor.

13. The connector assembly of claim 12 , wherein the first contact bend has a contact width narrower than a beam width of the second beam in a width direction perpendicular to a longitudinal direction of the second beam.

14. The connector assembly of claim 1 , wherein the first beam has a support protrusion extending from an exterior side facing away from the second beam.

15. A connector for a flat flexible cable, comprising:
a housing having a receiving passageway and a post extending through an opening in an insulation material of the flat flexible cable received in the receiving passageway, the housing has a main body with an outer portion and an inner portion disposed within the outer portion, the receiving passageway is defined between the inner portion and the outer portion, the housing has a securing element attached to the outer portion and rotatable with respect to the outer portion between an open position and a closed position, the securing element is rotated to the closed position aligned with the post when the flat flexible cable is received in the receiving passageway; and
a spring clip disposed in the receiving passageway, the spring clip having a first beam and a second beam, the second beam connected to the first beam and resiliently deflectable toward the first beam, the second beam has a first contact bend extending toward the first beam, the flat flexible cable is positioned in the receiving passageway between the first beam and the second beam and the first contact bend abuts a conductor exposed through the insulation material of the flat flexible cable to electrically connect the spring clip with the flat flexible cable.

16. The connector of claim 15 , wherein the housing has a latch retaining the spring clip in the receiving passageway.

17. The connector of claim 15 , wherein the post extends from the inner portion perpendicularly with respect to the receiving passageway.

18. A connector assembly, comprising:
a flat flexible cable having an insulation material and a conductor embedded in the insulation material, the conductor is exposed through a portion of the insulation material; and
a connector including a housing and a spring clip disposed in the housing, the spring clip has a first beam and a second beam, the second beam is connected to the first beam and resiliently deflectable toward the first beam, the second beam has a first contact bend extending toward the first beam, the flat flexible cable is positioned between the first beam and the second beam, the first contact bend abuts the conductor exposed through the insulation material to electrically connect the spring clip with the flat flexible cable, the spring clip is matable with a tuning fork of a mating header, the tuning fork has a first prong contacting the first beam and a second prong contacting the second beam to resiliently deflect the second beam toward the first beam.
